Floribunda rose plant named ‘KORfloci111’

ABSTRACT

A new and distinct variety of Floribunda Rose Plant, herein referred to by its cultivar name, ‘KORfloci111’, is provided which forms attractive, cup-like white colored blossoms. The vegetation is vigorous and the growth habit is very bushy and rounded. Attractive semi-glossy, medium-green ornamental foliage is formed. Very good disease resistance is exhibited. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Botanical/commercial classification:

Latin name—Rosa hybrida.

Common name—Floribunda Rose Plant.

Varietal denomination: ‘KORfloci111’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda Rose Plant of the presentinvention was created by controlled breeding during May 2005 atSparrieshoop, Germany by artificial pollination wherein two parents werecrossed which previously had been studied in the hope that they wouldcontribute the desired characteristics. The female parent (i.e., seedparent) of the new variety was an unnamed seedling (non-patented)resulting from a cross of the ‘KORpeligo’ variety (non-patented) and anunnamed seedling. The male parent (i.e., pollen parent) of the newvariety was the ‘KORfloci12’ variety (non-patented).

The parentage can be summarized as follows:(‘KORpeligo’ x unnamed seedling) x ‘KORfloci12’

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new Floribunda Rose Plant of the present inventionpossesses the following combination of characteristics:

-   -   (a) forms attractive cup-like white colored blossoms,    -   (b) exhibits a very bushy and rounded growth habit,    -   (c) forms vigorous vegetation,    -   (d) forms attractive ornamental semi-glossy, medium green        foliage, and    -   (e) exhibits very good disease resistance.

The new variety well meets the needs of the horticultural industry. Itcan be grown to advantage as ornamentation in parks, gardens, publicareas, and in residential settings. Accordingly, the plant isparticularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. Morespecifically, the unnamed seedling from the (‘KORpeligo’ x unnamedseedling) cross (i.e., seed parent) exhibits a light pink coloredflower, which is smaller in size and has less petals per flower comparedto the white colored flower of the new variety. Additionally, the‘KORfloci12’ variety (i.e., pollen parent) exhibits a crimson red with acream reverse colored flower, which has more petals per flower comparedto the white colored flower of the new variety and the ‘KORfloci12’variety provides a lower level of disease resistance compared to the newvariety. Moreover, the new variety can be readily distinguished fromnon-parental related similar varieties. For example, the ‘Meidelweis’variety (U.S. Plant Pat. No. 17,841) displays flowers with more petals,exhibits more fragrance, and produces a darker green foliage compared tothe new variety.

The new variety has been found to undergo asexual propagation at Wasco,Calif. and Cochranville, Pa. by a number of routes such as vegetativecuttings. Asexual propagation techniques in Wasco, Calif. andCochranville, Pa., such as vegetative cuttings, have shown that thecharacteristics of the new variety are homogeneous, stable, and strictlytransmissible by such asexual propagation from one generation toanother. Accordingly, the new variety undergoes asexual propagation in atrue-to-type manner.

The new variety has been named ‘KORfloci111’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonablypossible to make the same in color illustrations of this character, atypical specimen of the new variety. The illustrated rose plant of thenew variety was approximately two years of age and was observed atCochranville, Pa. while growing outdoors on its own roots in athree-gallon container.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart, 2015 edition). Theterminology which precedes reference to the chart has been added toindicate the corresponding color in more common terms. The descriptionis based on the observation of a two-years-old specimen of the newvariety, observed during May, while growing in a three-gallon containeron its own roots at Cochranville, Pa.

Plants of the ‘KORfloci111’ variety have not been observed under allpossible environmental conditions to date. Accordingly, it is possiblethat the phenotypic expression may vary somewhat with changes in lightintensity and duration, cultural practices, and other environmentalconditions.
